Given the anticipated rise in the global population by 2050, increasing food demand necessitates improved crop yields. Modernizing agriculture is essential to meet these demands. One significant advancement is the adoption of drone technology, particularly spraying drones, which can offer several potential benefits over traditional methods. While several studies have reviewed specific aspects of Agricultural Spraying Drones (ASDs), only a limited number have attempted to provide a broad overview. However, a comprehensive review focusing specifically on ASDs remains scarce. This review paper addresses that gap by exploring the various types and structures of spraying drones, their dynamics modeling and control strategies, path planning, swarm control methodologies, and droplet deposition processes. Additionally, it introduces criteria for selecting appropriate drones for specific applications. It also provides a detailed analysis of the advancements, challenges, and future prospects of spraying drones in agriculture, which may serve as a useful reference for researchers, practitioners, and policymakers interested in leveraging drone technology for precision agriculture.
